What is the difference between kotlinx.coroutines.CancellationException and kotlin.coroutines.cancellation.CancellationException? Thanks.

[Sam]

They're the same. In theory, cancellation behaviour for coroutines is defined in the kotlinx.coroutines library, so that's where the CancellationException would ideally live. In practice, the compiler has to know about cancellation exceptions for awkward reasons of compatibility, hence the additional kotlin.coroutines.cancellation.CancellationException declaration.

package kotlinx.coroutines
typealias CancellationException = kotlin.coroutines.cancellation.CancellationException

@Dmitry Khalanskiy [JB] it'd be nice if the stdlib one could be deprecated/hidden somehow to avoid confusion

Ok, I'll raise this proposal.
